Eyeglass testing equipment turns out to test these!

Eyewear testing includes eyeglasses lens testing as well as glasses frame testing. These tests are typically done before glasses leave the factory: frame deformation; dimensional stability at high temperatures; resistance to perspiration; bridge deformation; frame endurance test; ignition test; frame measurements and dimensional tolerances; check markings; lens retention; instructions and warnings on packaging; and nickel testing (metals only).

How to identify the good and bad glasses? Eyeglasses need to be tested by Eyeglass testing equipment before they leave the factory to confirm that they are qualified, and the quality and aesthetics of the eyeglasses can be judged. Aesthetics is a personal factor, while quality is a certain standard. The quality of eyeglasses refers to the quality of the lenses and the quality of the frames. What kind of lenses are qualified? What kind of eyeglass frames are qualified? Eyeglass tester in the end is to test some what? Please follow me to take a look at the following.

So how is it tested? What testing equipment is needed to test them? For different testing purposes different eyewear testing instruments will be used for testing. For example, frame deformation can be tested with a glasses bridge deformation tester, sweat resistance of glasses can be tested with a eyeglasses sweat tester, nickel testing (metal only) can be tested with a glasses nickel release tester for glasses, etc.
Now I would like to introduce you to the glasses frame bridge deformation tester. This eyeglass testing instrument conforms to ISO 12870 and EN1836 testing standards. It measures whether the frame has certain lens retention ability by twisting the frame angle several times to prevent the lens from falling off due to slight impact, which affects the wearing effect and ensures that the frame can be worn safely for more than 2 years.

The role of eyeglasses is to enable the wearer to see clearly, and let the consumer use the safety. Therefore, the lenses should be able to correct vision and protect the eyes, and the frames should be considered durable and have a certain degree of solidity, so it is very necessary to use eyeglass testing equipment to test the glasses before they are sold.
